how much are you willing to spend?

what do you consider fully built? everything upgraded just a little or 1000hp?

how long of a downtime are you willing to endure to get what you want/need?

you can get serious horsepower out of a stock sti crank case, so sleeving it is a waste of money. unless you mean sleeved for bigger pistons, but then you're still wasting money IMO. (friction losses, heat gained, ect.) if you want bigger, get a wetsleeved crawford block. it's 2.8L and is also way spendy.

so what is it that you want out of your motor?

Two very good questions. You'll get too many varied responses until you answer those.

5-10g motor can handle up to 600 hp and can handle anything that comes after it (boost)

How about a 2.8 closed decked, sleeved monster with forged crank/pistons and billet rods. How much assembled ?

I think how much $ you have to spend and power potential ,where in the RPMs you want that power are the number 1 and 2 details we need.

Don't forget you can't just spend $5k-$8k building a beastly motor and turbo system without upgrading trans, driveshafts, brakes, suspension, chassis stiffening, seats with proper harnessing, roll cage . . .

And dont forget tuning.. custom setups like you are talking about take quite a while to tune with a safe thresh-hold.

The 2.8l by crawford is a race motor, not a daily driver. About 2-3 people use this motor as a daily driver. If i where you i would look into worldoneperformance.com, they have some built blocks that look nice. Also Cobb has a couple of nice options, axis is also a decent choice. If i where you though i would stay away from crawford after all the problems they have been having with their motors. (just type in "bobblehead" under thread search and you will see what i mean).
